"Thank you to everyone who has embraced the gifts and talents of my beloved and amazing daughter," her mother wrote on her Facebook page late on Tuesday.

"I am grateful for your thoughts and prayers that are now guiding her to her next stop. Love Carries Mother."

Fisher made her feature film debut opposite Warren Beatty in the 1975 hit Shampoo. She also appeared in the hit movies Austin Powers, The Blues Brothers, Hannah and Her Sisters and When Harry Met Sally.

But Fisher is best remembered as the headstrong Princess Leia in the original Star Wars in 1977, her hair styled in futuristic braided buns.

She reprised the role in Episode VII of the series, Star Wars: The Force Awakens in 2015, and her digitally rendered image appears in the latest instalment, Rogue One: A Star Wars Story.

"She was extremely smart; a talented actress, writer and comedienne with a very colourful personality that everyone loved," Star Wars creator George Lucas said in a statement.

"In Star Wars she was our great and powerful princess - feisty, wise and full of hope in a role that was more difficult than most people might think."

Her Star Wars co-star Harrison Ford said in a statement: "Carrie was one of a kind ... brilliant, original, funny and emotionally fearless. She lived her life, bravely".

Fisher long battled drug addiction and mental illness. She admittedly smoked marijuana at 13, used LSD by 21 and was diagnosed as bipolar at 24.

In 1987, her thinly veiled autobiography, Postcards From the Edge, became a bestseller. It was adapted into a 1990 movie starring Shirley MacLaine and Meryl Streep.

She discussed the scandal that engulfed her superstar parents; her brief marriage to singer Paul Simon; the time the father of her daughter left her for a man; and the day she woke up next to the body of a platonic friend who had died of an overdose in her bed.

"I'm a product of Hollywood inbreeding. When two celebrities mate, something like me is the result," she said. At another point, she cracked: "I don't have a problem with drugs so much as I have a problem with sobriety."

In the past 15 years, Fisher appeared as a television guest star, perhaps most memorably as a has-been comedy legend on "30 Rock".

She also supplied the voice of a recurring character on the animated "Family Guy" for the past decade.

Carrie Fisher was smart, funny, talented, surprising, and always a hell of a fun time to be around. Family Guy will miss her immensely.
